Impact of farmer field schools on farmers' knowledge: the IPM experience in Sri Lanka

摘要

Two farmer field schools (FFSs) were conducted in the ricegrowing district of Matara, Sri Lanka, to disseminate integrated pest management (IPM) technologies. To ensure com-munity participation, two farmer organizations (FOs)--Pahala Vitiyala and Malana--confined to the two villages were selected as implementing organizations (IOs). The FOs selected 25 farmers each for the FFSs (50 out of 150 farmers) and separate FFSs were put up during the yala ricegrowing season, Sample size was nearly 34% of thetotal population.
